HIN211EIB

Overview

The HIN211EIB is a quad line transceiver manufactured by Intersil, designed for RS-232 communication applications. It operates on a single +5V power supply and features onboard charge pump voltage converters that generate +10V and -10V supplies internally. The device supports data rates up to 230kbps and meets EIA high-speed RS-232E and V.28 specifications. It includes ±15kV ESD protection on transmitter outputs and receiver inputs. The component is housed in a PDSO28 package and offers low power shutdown mode capabilities.

Feature Summary

• Integrated charge pump eliminates need for external dual polarity power supplies
• High ESD protection rating of ±15kV on I/O pins ensures robust operation
• Low power shutdown mode conserves energy in battery-powered systems
• True TTL/CMOS input compatibility simplifies interface with logic circuits

Applications

• Portable computers and laptop peripheral connections
• ISDN terminal adaptors and high-speed modem interfaces
• Instrumentation and UPS serial communication ports

Procurement Notes

Verify the specific suffix 'IB' against official Intersil or Renesas documentation to confirm pinout and electrical characteristics, as suffixes often denote package type or temperature range. Ensure the source document explicitly lists HIN211EIB rather than generic family members like HIN211EIAZ. Cross-reference manufacturer datasheets to validate moisture sensitivity level and RoHS compliance status before procurement.

Selection Notes

Select this component when designing systems requiring quad RS-232 transceivers with integrated charge pumps and high ESD tolerance. It is suitable for applications where ±12V supplies are unavailable and single +5V operation is preferred. Consider the PDSO28 package constraints and verify thermal performance for the intended operating environment. Compare with similar family members like HIN211EIAZ if different packaging options are required.

Part Context

The HIN211EIB belongs to the HIN211E family of RS-232 transmitters/receivers from Intersil, now part of Renesas Electronics. This family is characterized by high-speed operation, ESD protection, and single-supply functionality. The HIN211 variant specifically provides four drivers and five receivers, offering flexibility in system design compared to other family members with different driver/receiver counts.
